A study of the torsional behavior of reinforced concrete trough girder based on abaqus

With the rapid development of rail transportation, higher requirements are put forward on the environment, landscape, noise and other issues. Trough girders have gradually began to be widely used for its several advantages, such as lower building height, higher cross-section space utilization, better appearance, lower cost and noise reduction effect. In the present, compression and bending theory on reinforced concrete (RC) trough girder has been ideal. But torsional problems of RC though girder, due to the lateral sway force of train, are still difficult to solve entirely. In this paper, limited torque of RC trough girder was analyzed by using finite element analysis software ABAQUS. Also, concrete damaged plasticity model was adopted during analysis and the results obtained from the finite element analysis were verified against experimental results of other research. The result reveals that finite element analysis can be superior to simulate the torsion failure of RC trough girder.
